John W. "Jack" MacMaster, 76, a resident of Melrose, passed away on March 5, 2025 in Boston after a short illness.

Jack was born on October 6, 1948 at St. John's Hospital in Lowell, Massachusetts. The son of the late Hector J. "Mac" and Mary E. (Sliney) MacMaster, he was raised in the Highlands Neighborhood of Lowell. He was proud of his Lowell roots and his connection to the Highlands.

Jack received a faith-based education at St. Margaret's School, where he was taught by the Sisters of Charity of Nazareth. He was a communicant at St. Margaret of Scotland Parish throughout his childhood.

In 1966, Jack graduated from Lowell High School. As a student, he played basketball and baseball and was a member of the Business Club. After graduating from high school, he joined the United States Marine Corps. He later went on to attend the Andover Institute of Business. Jack worked for over 30 years in business, most of those years as a purchasing manager and later as a manufacturing executive. After his retirement, he worked part-time as a ranger and starter at Scottish Highlands Golf Course in Salem, New Hampshire.

On August 30, 1974, Jack married the love of his life, Kathleen A. Rogers. As parents, their sole passion in life was their four sons, upon whom they doted and raised together in the Mount Vernon Neighborhood of Lawrence.

Jack was a devout Catholic, praying the rosary two times a day. He enjoyed sports, particularly golf, and relished spending summers with his family at the beach. Jack took great pride in his Irish heritage, which he gained from his maternal grandmother, Julia (Gainey) Sliney, an Irish immigrant who lived with him throughout his childhood and with whom he had a special relationship.
